CIRCUIT DESIGN DEFINITION (continued): is very expensive, the number of tape-outs and stepping versions that can be made is limited. SPICE allows designs to be optimized before being sent off to fabrication foundries. Furthermore, unlike some circuitry, IC designs cannot be simulated by a breadboard mock-up because their design is integrated, rather than discrete in nature. SPICE can also take into account differences caused by manufacturing tolerances or parasitic capacitances and resistances.SPICE can perform DC, transient, pole-zero, small-signal distortion, sensitivity and noise analysis and can simulate results at different temperatures.
